They need to balance skills for 4v4 pvp before you get that kind of interest in it. I personally won't touch that stuff until, as a healer, I get an anti stun/purify get an even short recharge(60s or so), or they remove interrupt on hit/crit (make people use stun/silence intelligently). Not to mention if you're not r50 now, you'll be at an extreme disadvantage without gear/allocation points.
